That is a largely orthogonal issue (e.g. for eldoc it probably wouldn't
be a good approach).

But yes, I'd like to introduce a new kind of message that doesn't just
"display it now" but rather "display this for N seconds, but return
right away".  I.e. a form of "message" that would queue the message for
display and then a separate "thread" that would display the
messages queued.  This would avoid/solve many of the "my message was
overwritten by yours" problems.
